Ok, I have a TT Silent pure power LINK to Spec I can OC to only 238 FSB!? Why? Past that the system is fully stable as long as the system does not pushed to the limit of it's power. There are two simptoms that result if OC past 238FSB. -Reboot -Hang indefinitively No mather how much volt I push to the CPU, it just keep happening again. The system wont boot half the time if OCed to 245FSB and past 247FSB the bios can't even load, and I got a message ( I think ) but its all fuzzy whit many colors. Kind of an artifact. Sooo what do you Gurus think of that? I might be wrong, I think it COULD be the PSU.
